This man created 3 standards of length by dropping 1 meter long strings on a canvas and cutting the canvas along the profile of the string, which are called his standard stoppages. One of his early work uses earth tones to depict chess players and marked his departure from "retinal art," and Man Ray took several photographs of a cross-dressing alter-ego of this artist. In addition to dressing as Rrose Selavy, he created Rotary Demisphere and Bicycle Wheel, which were some of his kinetic works. Another of his paintings contains a set of white dots to illustrate the titular motion, which was famously called an "explosion in a shingle factory." For 10 points, identify this artist who painted Nude Descending a Staircase, and proposed that an upside down urinal be called Fountain.
